WebFOCUS Hyperstage Is the Default Storage Engine

The following information is displayed at the command prompt. In this example, MyISAM is shown as the default storage engine. You can combine the usage of different storage engines but you should avoid joining across storage engines as this can result in sub-optimal performance due to the use of the MySQL query engine. However, it can be quite useful in some cases to store query results in memory or MyISAM tables and do further manipulations of results.
